creates an object.
used internally to initialize the object.
returns the tag name.
takes an attribute name and returns the attribute value or undef if there's no attribute of the name.
returns any text (everything other than tags) before the tag. This typically returns white spaces between the tags for an open (start) tag, and the content of the tag for a close (end) tag, but don't count on that as HTMLs are not always well-structured.

You can replace the text by passing an extra argument.

takes an attribute name and its value to replace. You can also pass a regular expression if you replace arbitrary attributes.
takes an tag name and its value to replace.
